simple picture, quantum spins are like tiny magnets; any other spins or magnetic field in the vicinity could alter their states. In the framework of RPM for avian magnetoreception, it is thought that in CRY RPs can be in the form of anionic semiquinone FAD radical (\(\hbox {FAD}^{{\v...
As seen in section 4.1, it seems very likely that the neighboring clusters of galaxies can generate this field together, like assemblies of spin fields generate magnets for ferromagnetic materials. A fifth step, certainly the most complicated, would be to justify the value of \(K_1\) with a...
